write a script named compute.sh that is used to do simplearithmetic for the user. There should be no command line arguments.Instead, all values from the user should be prompted for and readin to the script using the read command.Specifically, you need to ask the user for two integers and anoperation string. The operation should be \"add\", \"sub\",\"mul\", \"div\", or \"exp\", for addition, subtraction,multiplication, division, and exponentiation, respectively. Yourscript should take the two numbers, perform the requestedoperation, and output the result. Here is a sample run:
[user@localhost ~]$ compute.sh
Enter an integer: 5
Enter another integer: 7
Enter an operation (add,sub,mul,div,exp):mul
5 * 7 = 35
[user@localhost ~]$
The script will have to translate the operation string to thecorrect operation using either a case statement or if/elsestatements. Note that you do not need to verify that the numbersgiven are actual numbers, but you DO need to verify that theoperation string is one of the five listed operations. If it isn'tone of the five, print an appropriate error message and exit.
Be sure to test your script thoroughly. When you're done,TAKE A SCREENSHOT (5) of the output of the scriptusing some example inputs.
TAKE A SCREENSHOT (6 – computer.sh) yourscript. I can’t grade if your screenshot is not readable. Biggerfont please! If you can’t control font size, please submit the fileas text format.
